FERDINAND J. HAGEN AND LUDYIG /VIELAND, OF NEV YORK, N. Y., ASSIGNORS TO THE EUREKA CIGAR MACHINE COMPANY, OF NEV JERSEY.

ClGAR-BUNCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 460,278, dated September 29, 1891.` Application filed October 2, 1890. Serial No. 366,855. (No model.)

T0 all whom, it may cori/067%:

Be itknoWn that We, FERDINAND J. HAGEN and LUDWIG WIELAND, both citizens of the 'United States, residing in the city, county,

and State of New York, have invented a new and useful Improvement in Cigar-Bunching Machines, of which the following is a specification.

This invention relates to the feeding mechanism of cigar-bunching machines, more particularly those in which the tobacco is fed from a supply-hopper through a throat into a bunch-mold by a feed-block Working in the throat, and when said mold is packed and the tobacco therein separated from the remainder, as by a knife, the bunch in the mold is carried toarolling and binding mechanism. An example of these machines is shown and described in United States Letters Patent No. 415,943, issued to the said Ferdinand J. Hagen, on ,th'e 26th day of November, 1889, to which patent reference is made` herein.

The main object of our improvement is to render the reciprocating feed-block so cornpensatin g that the different laterai portions of the feed-block Will yield elastically, according to the resistance offered thereto by the tobacco in the corresponding parts of the mold as the tobacco is packed therein, and

fto provide for regulating the degree of pressure at which the various portions of the'feedblock will yield, so that the tobacco will be packed uniformly in all parts of the mold and a cigar of uniform density thus pro duced.

A further object of the invention is to provide for the automatic regulation of the flow of tobacco to the compensating feed-block by the yielding of the same to an excess of tobacco in front thereof. Y

The invention consists of certain novel features of construction and combinations of parts by which the above ends are attained; and in order that theinvention may be clearly understood We shall iirst describe in detail the mode in which it is carried into effect, and then point out its several features in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in Which- Figure l is a sectional side elevation illustrating a feeding mechanism embodying our invention applied to a cigar-bunching niachine Which is in other respects similar to that described in the ferred to. Fig. 2 is a sectional plan View on the line X X, Fig. l. Fig. 3 is a cross-sectional elevation on the line Y Y, Fig. l. Figs. 4 and 5 are detail Views. k

Like letters of reference designate corresponding parts in the several figures.

A designates the frame-Work of the machine; A, thehopper in Which the loose filler 1s contained; B, the rag-Wheel by Which the iillerin the hopper is kept in motion; C, the vthroat to which the filler passes by the Wheel B; D, the opening in the top plate of the throat C; E, the feed-block vibrating inward and outward and reciprocating` longitudinally in said opening D; F, the mold, Which is in this instance solid and which oscillates from the mouth of the throatC to the rolling mechanism, (not showm) F', the knife by which the tobacco in the mold is separated from the remainder, and G the gang of cams by which the desired motions of the feed-block and mold are obtained, all of Which parts serve the principal functions ascribed to them in Hagens patent referred to.

To make the diierent lateral portions of the patent of Hagen refeed-block yield independently ofeach other according to the respective resistances which they meet from the packing of the l'iller in the mold F,Wh1ch is preferably cigar-shaped,

like that described in the saidpatent of Hagen, We construct the feed-block of a plurality of-in this case three-longitudinalsections E and mount them to slidelengthivise independent-ly of each other in a guide-block carrier H. The carrier H has side plates H on opposite sides of the feed-block, between which side plates the sections E are held from vertical movement on thecarrier, While allowed their longitudinal compensating feeding movement thereon by a transverse guideplate J, rigidly connecting the side plates Il and extending through coincident longitudinal slots gli in the several sections E. Each block-section E is provided on its for- IOO Ward end With an upwardly-extending lug E2;

to which We pivot to allow vertical play a longitudinal guide-bar O, and We pass the rear ends of the several corresponding guide-bars O loosely through a transverse guide M, which is iixed to the hanging arm M2 of an angle-lever M, the other arm of which follows a cam, substantially as in Hagens patent aforesaid, and gives the longitudinal feeding motion to the feed-block-carrying guide M. On each guide-bar O, between said guide M and the respective lug E2, we place a coiled spring L and a screw-nut O for adjusting the tension of the spring, and on the end of each guide 'bar O, back of the guide 1W screw a collar-nut O2, having a convex bearing against said guideM, so that as said guide M is reciprocated longitudinally, as before stated, the several block-sections will be likewise reciprocated simultaneously, while an increase in resistance to any section over the others will cause the 'said section to be retracted relatively to the others, the respective spring L yielding to permit said retraction. By the tension-adjusting nut O on each guide-bar O the proper yielding point of each section can be regulated to a nicety.

The side plates H of the feed-block carrier H are provided with rigid arms P, which are in this case pivoted to lugs Q on the top of the throat frame-work, so that the carrier H can vibrate and with it the sectional feed-block E upward at the end of the forward feeding movement of the said feed-block and downward at the end of the rearward movement of the feed-block. Said vibrating motion is here given to the carrier and feed-block by links R, connecting the side plates H 'of the carrier with the slotted, arms S of an anglelever S, which is fulcrumedat its angle to the frame-work of the machine and has its other arm engaged with a cam, substantially as described in Hagens patent before mentioned.

To automatically check the iiow of tobacco from the hopper when there is an excess of tobacco in front of the feedblock,which will cause the same to be unduly retracted, we arrange a hanging cut-off T in an opening in` the front of the hopperA and inline with the feed-block, so that the retraction of the same will cause it to press the cut-off T into the hopper toward the feed-wheel, and thus check the flow of tobacco therethrough. The cutoff T will swing back by gravity when the pressure on the feed-block is relieved.

The shaft of the feed-wheel B is mounted to revolve in adjustable bearings U, (shown in Fig. 5,) pivoted to the sides of the hopper A and arranged to be secured in position when adjusted by ordinary set-screws (not shown) passing through the slots V.

We claim as our invention* l. ln a cigar-bunchingmachine, the combination, with the mold, the feed-throat, the feed-block, and the feed-block operating mechanism, of an elastic connection between the feed-block and its operating mechanism, substantially as described.

4. In a cigar-bunching machine, the combination, with the mold, the feed-throat, the feed block, and the feed block operating mechanism, of an elastic connection between the feed-block and its operating mechanism, and means for adjusting the tension of said elastic connection, substantially as described.

In a cigar-bunching machine, the combination, with a mold and feed-throat, of an inwardly and outwardly vibrating feed-block carrier, a plurality of longitudinally-Working feed-block sections on said carrier, longitudinal guide-bars pivoted to the respective feedblock sections, a longitudinally-reciprocating guide on which the several guide-bars work, and elastic connections between the said guide-bars and the said reciprocating guide, substantially as described.

8. In a cigar-bunching machine, the combination of a plurality of feed-block sections, guide-bars connected thereto, a longitudinally-reciprocating guide on which said guide-bars work, springs between the guidebars and said reciprocating guide, and springtension-adjusting nuts on said guide-bars, substantially as described.

9. In a cigar-bunchi`ng machine, the combination, with the hopper, the feed-throat, the mold, the feed-block, and feed-block-operating mechanism to which the feed-block is yieldingly connected, of a hopper-supply cutoff operated by an undue yielding of the feedblock, substantially as described.
